Basic elements of mesh die cutting

1 mesh

The mesh number is a unit indicating the density of the mesh weaving (the amount of mesh contained between the meshes having a length of 1 inch)

2 wire diameter

The diameter of the wire is the thickness of the wire. As shown in the figure as TD

3 thickness

The thickness is the thickness value (measured value) when the mesh is in tension and is in a static state.

4 opening

Opening is a method used to indicate the size of the holes between the meshes. The opening is determined by the thickness of the wire and the mesh.

5 opening ratio

The open area ratio refers to the area occupied by the gap in the unit area expressed by the percentage of the mesh. The larger the percentage, the larger the opening ratio of the mesh.

6 acoustic resistance rate

Sound resistance rate = sound pressure / particle speed. It is the most important parameter related to sound. The smaller the value, the smaller the barrier to sound.

Mesh die cutting product material classification

Polyester PET

Features: low shrinkage, high strength, acid aging and environmental protection

Self-absorbent

The aperture does not change after encountering water

Nylon PA

Features: high elongation

Water absorption

The hole diameter changes after water contact, resulting in a change in the acoustic resistance rate.

Unstable acoustic performance
